Setup
The SDP-RFD AC-3
®
/RF Demodulator
chassis is barely four inches deep to
allow it to be positioned adjacent to an
AC-3
®
-capable player’s RF output. This
minimizes the required RF-signal cable
length to reduce any RF interference. As
the unit uses automated switching, and
draws very little power, you can literally
set it and forget it.
To set up the SDP-RFD:
•
Connect a 75
Ω
coaxial cable
between the SDP-RFD rear panel
RF (AC-3
®
) input and the laser disc
player's RF/AC-3
®
output. Keep
this cable as short as possible to
minimize RF interference.
•
Connect a 75
Ω
coaxial (or optical)
cable between the SDP-RFD
S/PDIF input and the laser disc
player’s digital output.
•
Connect a 75
Ω
coaxial cable
between the SDP-RFD S/PDIF out-
put and the SDP-2 COAX 1 digital
input.
•
Recommended: Connect a 5-pin
DIN cord (not supplied) between
the SDP-RFD PWR CTL input and
the SDP-2 PWR CTL output. This
allows the SDP-RFD to power on
and off with the SDP-2. If this con-
nection is not made, the SDP-RFD
will turn on whenever its AC
adapter is supplied power.
•
Optional: Connect any additional
components which allow remote
turn on (such as Synthesis’
S Series of power amplifiers)
to the SDP-RFD rear panel PWR
CTL (LOOP THRU) connector.
•
Connect the AC adapter provided
to the POWER jack.
Once the SDP-RFD is properly con-
nected, set the front panel INPUT
SELECT switch for the appropriate type
of NON-AC-3
®
/RF digital output you are
using on your laser disc player. (Most
laser disc players have only one.) Set
the RF TIMING switch according to the
chart provided on page 2. Once you
have completed the connections and
setting of the front panel switches, all
functions are performed automatically.
LEDs on the front panel are provided to
identify the operational state.
Maintenance
The SDP-RFD requires no maintenance.
However, it is good electrical practice to
clean all connectors once a year. Clean
the exterior surfaces of the unit with a
soft, lint-free cloth, dampened with
warm water.
